2015-09-29 08:14  Clicks:
There is greater risk of fire in public place, so flame retardant measure is necessary. But as the difference of region and culture, there are all kinds of flame retardant products and items in different place, in view of this, after a lot of discussion, the experts determine to test the property of flame retardant products according to the following classification.
 
1. Flame retardant construction products: for the same material and same structure of building materials products, if the most thickest and thinnest material can meet the requirements at the same time, the material that the thickness between the two also can meet the requirements. ( FR flooring material: the same material, if the most thickest and thinnest material can meet the requirements at the same time, the material that the thickness between the two also can meet the requirements.)
 
2. FR textile: the same material, if the density largest and the smallest of FR textile can meet the requirements at the same time, the material that the density between the two also can meet the requirements.
 
3. FR plastic/rubber: the same material, if the thickest and the thinnest FR plastic products can meet the requirements at the same time, it will be regard as that the material that the thickness between the two also can meet the requirements. (Note: when sample preparation, it can cut sample from the same thickness in normal parts of outer shell, if the size is not conformance, can joint together in proper way.)
 
4. FR foamed plastic: with the same density, if the thickest and the thinnest FR foamed plastic can be meet the requirements at the same time, it will be regard as that the material between the two can meet the requirements.
 
5. FR furniture/assembly: with the same material and construction, if large size furniture/assembly can meet the requirements, it will be regard as that other small size ones also can meet the requirements.
 
6. Electric wire and cables: with same construction (inner and outer sheath, armor layer, filling material, insulating material etc..) , if the largest outer diameter and the smallest one can meet the requirements at the same time, it will be regard as that the products’ diameter between the two also can meet the requirements.
